And what I'm saying is that I don't agree with that statement because success shouldn't be automatic, even if the only cost is time.
Do you have your players roll for every single thing they do in the game?
It seems you keep assuming that my scenario "there is no time limit to how long they can try" is the same as saying "they will automatically succeed anyway"
That is true within the bounds of the example you set forth and given what the rules say.
But I would encourage you to think about the question I ask above. Because I bet you grant auto-success to all manner of things the PCs do already as those things are trivial and without complication.
